Description
Technical field
The present invention relates to a kind of method that is used for braking rail driving.
Background technology
Known have a rail driving that has multiple brake system.For example in DE10135797C2, put down in writing a kind of rail driving that has an electrically operated and mechanical friction brake.The kinetic energy of rail driving must be absorbed by existing brake system in each braking procedure.In electric actuated brake system, this otherwise realize by kinetic energy being fed back to the supply network that can feed back, or realize that by so-called braking resistor wherein, kinetic energy at first is converted into electric energy by the drive system of starter/generator effect.Electric energy is transported to braking resistor then, and last braking resistor is translated into heat energy.
In the electrodynamic braking of feedback, the efficient of braking is relevant with the degree of the recuperability of supply network.Recuperability is by the absorption power and the availability decision of supply network.If only have a braking resistor in the electrically operated brake system, then brake efficiency is by braking resistor restriction itself, and this braking resistor only is designed for the certain ceiling capacity of thermal cross over.In addition, braking resistor has improved the axial load of rail driving, and since in rail driving the assembly space of limited existence be disadvantageous.In order to consider described requirement, braking resistor light as far as possible and design according to prior art littlely.
When the brake action of electric actuated brake system was not enough, all dynamic (dynamical) braking energys must be converted into heat energy by means of the friction braking of machinery.Yet, especially when high speed, can cause brake plate to wear and tear in advance and damage to this superpower input of brake plate.Braking below the velocity limit value effect that wearing and tearing are played to brake plate is less.Therefore, the 1 corresponding design effectively of known friction brake is even if make the irreversible damage that also can not cause drg to the higher power of brake plate input and/or energy.Yet this causes the friction brake of corresponding cost costliness.
Summary of the invention
Therefore, technical matters to be solved by this invention is, a kind of method that is used to brake the rail driving that has electrically operated and mechanical friction brake is provided, and this method is with low cost and can use reliably, wherein can omit the braking resistor that takes up space.
The present invention solves this technical problem by a kind of like this method, this method can be used electrically operated drg and the mechanical friction brake that feeds back at glancing impact in supply network, wherein, but electrically operated drg is determined in supply network in the degree of the feedback of the braking energy of glancing impact generation, and has a regulon, wherein, regulon makes the speed of rail driving and the degree of recuperability be complementary in this wise, makes friction brake be prevented in the damage of glancing impact.
According to the present invention, the recuperability of supply network is monitored in motion incessantly.Be lower than the critical value of predesignating if find the degree of recuperability, so under the situation of braking to the too high energy of brake plate input of the friction brake of machinery.By the solution of the present invention regulation, the speed of rail driving limits in this wise, and the damage of friction brake is prevented.In framework of the present invention, can give up braking resistor fully.Therefore, cause a kind of cheapness and more failure-free rail driving simultaneously by method of the present invention, its brake system has the electrically operated drg of the parts that do not take up space.
Degree ground type and mode how to measure recuperability in framework of the present invention are arbitrarily in principle.Yet the degree of recuperability advantageously is determined in braking procedure.This is for needing minimum cost by method of the present invention, but wherein the friction braking of machinery is added with higher load once in braking procedure, wherein, determines the degree of a low excessively recuperability for given speed.Yet this is acceptable.
Suitable is, determines a minimum hardening time of mechanical brake after each braking procedure, and the maximum speed allowable of rail driving is limited so longways, is exceeded until minimum hardening time.Minimum hardening time is for example by determining the detection of the temperature on the brake plate by temperature sensor.When the temperature that records is higher, prolong minimum hardening time.If the drg of machinery, for example brake plate is enough cooled off, and can improve the maximum speed of rail driving in framework of the present invention once more.
Suitable is that the degree of the recuperability of supply network is determined by detect the electric current and/or the voltage that feed back in supply network at glancing impact.Also detect voltage if for example both detected electric current, can directly determine the energy or the power that are fed back.The energy of feedback is for example made comparisons with pre-determined threshold energy.If the electric energy of feedback is lower than described threshold energy, the maximum speed of rail driving will descend so.Under this speed, the drg of machinery can with the residual braking force of electrically operated drg reliably and not wearing and tearing ground braking rail driving together.
The braking force that regulon is advantageously provided by electrically operated drg and mechanical brake according to predetermined braking rating speed reduction degree adjustment and.Braking rating speed reduction degree value is for example given by train driver.Use is netted so that unnecessary kinetic energy is fed back to electric energy once more and is powered in electrically operated drg response regulation unit at first after receiving braking rating speed reduction degree value.If the braking rating speed reduction degree that provides by electrically operated braking is not enough, so Ji Xie drg response regulation unit additionally wherein, produces such friction force, that is, obtain always to brake the rating speed reduction degree as far as possible accurately corresponding to braking rating speed reduction degree.In order to determine to brake the rating speed reduction degree, regulon and appropriate survey sensor, for example wheel speed sensor connection.Wheel speed sensor is transferred to regulon with the vehicle wheel rotational speed value, and this vehicle wheel rotational speed value is corresponding to the wheel revolution within a certain period of time of rail driving.The girth of wheel and diameter are known, so regulon can be determined momentary velocity by the revolution of unit time.Can finally determine braking deceleration from momentary velocity in time change braking procedure.
According to a kind of corresponding favourable expansion, the degree of the recuperability of glancing impact is determined by the braking force of measuring mechanical friction brake.As mentioned above, at first use electrically operated drg at a rail driving glancing impact, so that kinetic energy is converted into electric energy.Mechanical brake for example only just uses when the braking deceleration that provides by electrically operated drg is not enough.Therefore, can be by the counter recuperability of releasing supply network of the payload of mechanical brake.The payload of mechanical brake for example realizes by the electric current in the braking circuit of Pneumatic pressure in the brake cylinder of hydraulic pressure in the brake cylinder of measuring hydraulic brake or pneumatic braking device or the drg by measuring electromechanical.
According to a kind of favourable expansion of the present invention, cross the maximum speed allowable that limits vehicle after low constantly for maximum speed allowable in the degree that repeatedly one after the other recognizes recuperability successively, wherein, the restriction that continues shown in only can be by the personnel's cancellation through permission.Can satisfy high safety requirements in this way by method of the present invention.
